1) It is lawful under the statutes of the state of Oregon.
2) It is his RIGHT under BOTH the federal and Oregon state Constitutions.
3) I have open carried since August of 2009 EXCLUSIVELY and have encountered exactly ONE person who was actually afraid of my weapons......a small child in a very liberal town who was far too young to have developed any fear of weapons on her own.
4) Due to Warren Drouin's activism, Medford police no longer ILLEGALLY detain individuals, seize their property, run their ID, run their serial numbers, drag OC'ers out of movie theaters, or cuff law abiding citizens who merely have the audacity to walk into the police station with a handgun on their side. He has made a difference for the better.
5) While long gun open carry is not condoned on this site, it was instrumental in defeating a set of local ordinances proposed in Ashland. Long gun open carry in their town, as part of the overall strategy, basically forced them to open their eyes and realize that they could not stop open carry but would actually bring more, and more visible, open carry to their town. A town who's economy depends upon tourism. The comments of councilors when they voted 5-1 (plus the Mayor stating that he would have voted no) specifically mentioned the "in your face" activism that they had seen as a result of their consideration of the ordinances.
6) Make no mistake, those who wish to restrict our right to keep and BEAR arms will NOT stop trying to do so simply because pro second amendment folks stop doing activism. It doesn't matter if you open carry or conceal, they want to get rid of guns and merely putting them out of sight (or less visible) will NOT stop that. They are after them PERIOD and no amount of capitulation or compromise will change that FACT. In FACT, compromise is why we are where we are.
Bottom line, like it or not, it's his RIGHT and lawful. So, you either support his second amendment RIGHT or, you are part of the problem.
